It appears we have some interest here. From what I gather after reading the synopsis for both, that the one wanted is more than likely a 1982 TV adaptation of the movie done in 1975. New Cast etc. That will surely make it harder to find. To do some research I would need the Studio etc and then contact them. Never say never as someone does have the answer.
I have a good friend who is an actor and did some of the Dallas series with "The Hag" I will email him for the straight scoop.
By the way the
www.imdb.com site is a great reference, I use it all the time. Another great search site is
www.copernic.com they have a free download that will compete with the best of them..
